Article Synopsis
- PET is highly sensitive and has excellent resolution, making it useful for treating and preventing major diseases, but there is potential for improving its readout circuit.
- A new LIGHTENING® PET detector was developed using a LYSO crystal array and SiPM array, along with a dual time interval (DTI) sampling method for better digital pulse acquisition.
- The design includes a semi-cut light guide that enhances resolution, and results showed the detector achieved a 14.3% energy resolution and 972 ps coincidence timing resolution, indicating it's suitable for high-performance time-of-flight PET scanners.
This work focuses on event energy measurement, a crucial task of scintillation detection systems. We modeled the scintillation detector as a linear system and treated the energy measurement as a deconvolution problem. We proposed a pulse model based iterative deconvolution (PMID) method, which can process pileup events without detection and is adaptive for different signal pulse shapes.
